PCB testing methods during manufacturing and assembly?

We plan to visit factory next week. Could we know more about how many basic PCB testings in EMS field?
  1. VISUAL INSPECTION
  2. IN-CIRCUIT TESTING (ICT)
  3. FLYING PROBE TESTING(FPT)
  4. AUTOMATED OPTICAL INSPECTION (AOI)
  5. AUTOMATED X-RAY INSPECTION(AXI)
  6. FUNCTIONAL TESTING (FCT)
  7. BURN-IN TESTING

What Others Are Asking

Do electronics distributers test each component before sending them out?

I’m trying to decide whether to order components direct from manufacturers in China or from distributors in the US. If I have to test each component either way, I’m not sure if it’s a counterfeit, especially when prices are 100x more expensive from distributors.

When should I choose 2 layer PCB or 4 layer PCB?

Our brand was focused on common electronic product with single PCB. And this year, we plan to develop a smart range which may require multiple layer PCB. Want to know more about 2 layer PCB or 4 layer PCB.
